Lineage switch is a very rare event in blastic crisis of chronic myelogenous leukemia (CML-BC). To our knowledge, only three cases of lineage switch between lymphoid and myeloid/myelomonocytic lineages have been reported in the literature. Here, we report a novel case of imatinib-resistant CML-BC, in which the blast lineage switched from biphenotypic to B-lymphoid.
谱系转换在慢性粒细胞白血病急变期(CML-BC)中是非常罕见的事件。据我们所知,文献中仅报道了3例淋巴系与髓系/粒单核系之间的谱系转换。在此,我们报告1例伊马替尼耐药的CML-BC新病例,其中原始细胞谱系从双表型转换为B淋巴细胞系。
